GBU4M-BP

Overview

The GBU4M-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a 4 A average forward rectified current rating and a 1000 V maximum repetitive peak reverse voltage. The device utilizes glass-passivated chip junctions for enhanced reliability and surge overload capability. It is housed in a GBU surface-mount package with solder pad termination, measuring 22.3 mm in length, 18.8 mm in height, and 3.56 mm in width. Electrical characteristics include a maximum forward voltage of 1 V at rated current and a reverse leakage current of 5 µA. The component supports an operating temperature range from -55 °C to +150 °C and can withstand a maximum surge current of 150 A.

Feature Summary

• Glass-passivated chip junctions provide high reliability and protection against voltage transients.
• High surge overload rating ensures robust performance during transient current events.
• Surface-mount GBU package design facilitates automated assembly and compact PCB integration.

Applications

• AC-DC power supply circuits requiring high-voltage rectification
• Bridge rectifier configurations in industrial control systems
• General-purpose power conversion applications

Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official MCC documentation before procurement. Confirm RoHS compliance status and REACH SVHC declarations as required by project specifications. Ensure the component matches the intended GBU footprint and pinout configuration for your PCB layout. Check for any end-of-life or not-recommended-for-new-designations that may impact long-term availability.

Selection Notes

Select this component when a 1000 V reverse voltage rating is necessary for single-phase bridge rectification. The 4 A current capacity suits moderate-power applications where surface-mount technology is preferred over through-hole solutions. Consider the thermal management requirements associated with the GBU package size and the specified maximum junction temperature of 150 °C.

Part Context

The GBU4M-BP belongs to the GBU series of single-phase bridge rectifiers from Micro Commercial Components. This series offers various voltage ratings within the same physical footprint, allowing for design flexibility. The 'M' suffix typically denotes the 1000 V voltage class within this product family, distinguishing it from lower voltage variants like the GBU4B or GBU4D.

Replacement Considerations

Direct replacements must match the 4 A current rating, 1000 V reverse voltage, and GBU surface-mount package dimensions. Verify compatibility with existing PCB footprints and thermal constraints. Consult official cross-reference lists from MCC or other manufacturers for equivalent components with identical electrical and mechanical specifications.
